Reusing MPlay instances
MPlay can listen for renders and flipbook requests from Houdini.
To have MPlay listen for flipbooks, start it with mplay -K or
    mplay -flipbook. To have MPlay listen for renders, start it with
    mplay -k (lowercase k) or mplay -render.
A flipbook or render will automatically start an MPlay session if no MPlay session is listening for them.
